Add curl options to OPI

For an acquisition to be made with curl in cases where graphicsmagick doesn't seem to take redirection well, you can now click on "Use Curl"->"YES".

If you need authentication, add an authentication file in the server and its path to the "Authentication file" text entry. Should be in the format:

user = "myuser" password = "mypassword"

You can choose the http authentication method and SSL verification options.

I have tested it with hikivision camera. It works.
